After seeing this movie, and several of the comments bellow, I am forced to ask "Was this really that bad?". Perhaps "War, Inc." is not all the hype that it has gotten. It isn't, even to the point where I may feel betrayed by the trailer. But, in answer to the question, I would have to say that it wasn't that bad.
"War, Inc." brings several good things to the screen. This is a satire, that in itself is worth something to me. That the subject of gloomy documentaries can be humorous and poignant to the subject. This is a good thing, and it is something that is lacking in this world with gloomy documentaries.
Another point about this movie, it is not really indie; indie really is just some guys with a camera and little or no money, with the idea that they have something overwhelmingly important to say by not doing much at all with an audiences time (as in "The Life Aquatic with Steve Zissou", which itself isn't very indie anyways) and that can yield perfectly fine results as well. "War, Inc." differs from this in that, although it is in limited release, it has many of the blockbuster qualities, seeing it, one realizes that the production was hardly pressed for money. This movie also does have something to say to the world, maybe it is something that you hear everyday on NPR, but that does not make this movie any worse for what it is.
As for some actual reviewing, as opposed to simple opinions on what "War, Inc." is or is not, I would have more positive things to say for it than some of what has been said here. But not, however, glowing with endless lines of praise for it. As I have said, it was even a bit of a let down. But, Cusack does mount a tripled outfit as writer, actor, and producer which may be somewhat of a stretch, having some amount of control on almost every aspect of the film (except, I assume the streak of peroxide blond hair he sports). Never the less, this movie does not loose itself to John Cusack, which is one of the best things the movie does not do.
Also, as I said before, "War, Inc." brings something to the audience in that it allows a chance to have some amount of joviality over the ugliness of the truly grotesque world we happen to live in. This is not a problem, "South Park" is a masterwork of this and it, like "War, Inc." gives us pause for humor as well as self reflection on what we do. This is something to be commended.
The point is that "War, Inc." although a let down, I found to be just fine for what it is. This cannot be said for some other movies, movies that fit into really another category all together or lack some vital part to them. "War, Inc." does not reserve itself to such halls. In its case, one should find an amount of middle ground for what it is as an existential work of satire which it lives up to perfectly, and a movie which is more second rate but not totally problematic.
